MEAT SAWING 0Rv CUTTING MACHINE.

Tooll whom it may concern: I j I Beit known that I, GEORGE THOMASFRANcisoo, 'residingat Highland, in the county of San Bernardino andStateof California, have invented certain new and useful Improvements inMeat Sawing" or. Cutting Machines, of which the following is which themeat islaid, and providing a motor-driven cutting mechanism susceptibleof universal adpistment whereby the meatmay be sliced and the bonessawed,-as;conditions may require.

In 11911 10113 detailed nature the invention resides in providingamotordriven shaft on "which .a shifting carriage or frame is horizontal axis.

mounted and held from turning on the shaft, means being provided forshift-mg such frani'calong the shaft a main frame is supported on theshaft to turn thereon and the turning movement of this frame ismaintained within certain limits by spring and abutment devices so thatunder normal conditions the mainframe will set vertically; the mainframe carries an auxiliary frame that in turn carries the saw. orcutting tool The auxiliary frame" is mountedto turn one vertical axisand the saw carrying frame is mounted .to turn on A saw holder is.reciprocal ly ll'lOUlltedill the carrying frame and is reci 'irocatedthrough a link connection .with a'cranlr shaft thatis supported by themain frame'and driven through gears from the main shaft, suitableclutching devices being pivoted to throw the gears into and out ofoperation, and means are also proi'idedfor raising and lowering the sawwith relation to the table in planes parallel to itself, the main framebeing swingableon the main shaft so that the saw may be swung up awayfrom the meat, or other article heingworked upon, when desired.

,In its more subordinate nature-the inven- ,tlQII'alSO comprises thosenovel details of construction, combination and arrangement Figure 1, isaperspective View showing Specification lat Letters Patent. l atent d lula'lgll. Application filed June 7, 1910. Serial No. 565,442.

Fig.6 is a detail perspective view of the main frame. F '7, is a detailperspective view of the auxiliary frame. Fig. 8, is anenlarg'ed detailView of the clutching mechanism.

Pivoted at 1 on' the top l isan adjustable top 1. that is movable on its pivot by apinion 1 on" when1 that is mounted in the top 1 and turned by a crank 1, the pinion 1ineshing' wit h a rack 1 on the shiftable :top 1, a's indicated. Acrank-1 on the shaft 1 serves as a means by which Fig. 5, is a detailperspective view,

the shaft may be turned and the crank 1 is of the'pawl type to engage arack member ll "on the top to hold the shaft from turning,

and., tliereby hold' the top 1 immovab1e.

The meat to becut or sawed is placed on the block or topvl'f. v f

Projectingforwardly from'the table 1 is .a'pair fof brackets 2 havingbearings 2 in which the main shaft 3 is mounted. The

- sh"aft 3 carries a drive pulley 3" and a fly ,wheelfi Longitudina-llymovable on the shaft 3 is a shifting frame 4 having forked. bearingportions 4?, through which the shaft 3 passes. The frame 4 also has aportion 4: that projects into a slotted guideE Z" between the brackets"2 to prevent the frame 4 turning on the shaft 3 while still permittingit to be shifted longitudinally on the shaft. The shifting of theframes: is done by-a cable 5 whose ends are attachedat 5 to the forks 4and'the cable 5 passes over idler sheaves 6 6 ,on,the brackets-2 and isii 60 that]projegas out of the hub and..tl1e

wound on a drum 7 on the shaft 7 that is supported in bearings 7 beneaththe table top 1. The shaft 7 may be turned by a crank 7 or otherequivalent device.

The main frame 8 has forked bearings 8 to receive the shaft 3 and beheldbetween the forks 4 of the shifting frame 4. The main frame 8 swivelsonthe shaft 3 and has its movement, limited by shoulders 4 on theshiftingframe 4. Theseshoulders 4 act together with a sprlng 9 tosustain the main frame in a vert cal position under normal conditions.

The frame 8"v has a bearing sleeve 8 and.- a bearing lug 8 to support anauxiliary frame 9 that has bearing portions Q -9 for the cylinder 8 andlug 8 respectively. The frame 9 is susceptible of vertical movement insuch main frame for purposes later to appear. The frame 9 also hasbearings 99, on projecting sleeves of which the saw carrying frame '1015 mounted. The

- frame 10 comprises a substantially U-shaped 12 slidesin' the bearing 9and whose oppoframe 9. The

stock 1O having bearings 10"'10 to receive tl'iebearings 9--9 one ofwhich bearings 10 is 'ofmlisk forin to engage a retain-,

lug pin 9 ?f'on--'the frame 9 to hold the sap frame "10 inplace." 'Thesaw frame 10 also includes a section 10 that is removably secured to apro ection 10*; on the stock 10 and has a handle 10""at'its forward endby whichthe saw carrying-"frame may be turned on an axis at right anglesto tnat'on which the frame 1.0;1's"niounted.

The saw carrying frame has bearingslQ -elO and 10 'forthe saw holder 11which recipro'catesin thejframe 1O and-has rods 11"-11" that play in thebearingsIO -JO and the si'w holder ll'also has a rod 11 that operates inthebearing 10. The rod 11 being longer than the rod '11 projectsthfough-the-baring 9 of the frame 9 and -is swivell-y securedto thepitman-12-whose end siteend-12 slides in a bearing 9*- on--the 12 forthe crank 13; The crank .13 is carried b the crank shaft 13that..pas;ses

tl11011g ythe bearing '8" and carries a pinion.

14which meshes with a master gear 15 on the main shaft 3. The sawholderhas portions'r11 toreceive and hold the saw, knife or other suitablecutting tool 11.

The-main shaft 3 has a key groove 3 and the gear 15 has a hub m in whicha key 15 is pivoted to-enterthegroove 3 and cause the gear to, turnwiththe shaft.

16'is ai shifter that is pivoted. at 16 to t-hch mainframe and has aneye 16* to receivethe hub 15 and'key 1 5?. The key 15 has'a' heel latehor key has-a fulcrum. bearing'lfi for the hub. The shifter 16is normallyheld over the clutching end of the key 15 to hold the same 1n the groove,3, as clearly shown in pitman 12 has a slottedyoke- Fig. 8 of thedrawings. When it is desired to cause the master gear to run loose onthe shaft 3 the shifter 16 is shifted over the heel 15 thereby-causingthe key t6 turn on its fulcrum-and disengage the key groove 13 in theshaft.

17 is a vertical shaft that is mounted'in bearings 18 in the main frame.On the lower end of the shaft 17 is an arm 17. which connects with theshifter 16 .to shift the same. The shaft 17 is turned by a lever 19 onthe top of the main frame 8, which lever is connected to the crank 17 onthe rod 20, as shown. A spring 21 holds the lever 10 in a position tohold the shifter 16 over the clutching end of the key 15 to thereby keepthe mastergear 15 clutched to the shaft 3. v

In order to raise and lower the'auxiliary frame on its ends to cause thesaw or cutting tool to be raised or lowered 'parallel to itself, I p1ovide a fork 22 whose ends are slipped under the auxiliary frame 9 belowthe hearing 3.)" and straddling the bearing 8", and the ends of thefork22 are curvedat 22' so that as the fork is moved one way or theother,

the frame 9 will be liftedor lowered, "a's'the case may be; The fork 22is operated'by a bell crank lever 23 that is fulcrume'd at 23 to themain frame and connected-by a 'rod 241 to'the handle 22 of the fork22,as shown, a spring 25 serving to keep the fork in a normal position asshown.

The shaft 3 is driven from an suitable motor 2G that is belted orotherwise conupper end of the shaft 17 by a connecting.

nected'at 27 with the shaft 3-.

'In operation the meat to be cut is placed on the shifter table. topwhich "is thenad justed to present the meat in the pro er position forcutting,' after which, (it benigassumed that the motor is running todrive the shaft 3) the lever is shifted to .cause the shifter 16' tobring the key 15 intoem gagement with theslot ofthe shaft '3' to 'lockthe master gear to the shaft so as to set the cutting tool intoreciprocation; after which the operator grasping the hand piece of thesaw carrying frame guides it -to the work as conditions may require; Byproviding the universal (mounting of the saw, as shown and described,the saw may be made to cut'the meat in any desired direction. At thebeginning of the cutting operation the auxiliary frame may be adjustedto its uppermost position "and lowered through the medium of itslowering devices as the out proceeds. hen it isdesiredto make the nextout it is only necessary to shift the shifter, frames-long the shaft-anamount necessary to bring-thesaw)into po rsitionto cut the next pieceoff of the main part of-the meat onthe table top.-
